S <br /> Simple Heating System Size:Washington State <br /> This heating system sizing calculator is based on the Prescriptive Requirements of the 2015 Washington State Energy Code(WSEC)and ACCA Manuals <br /> J and S.This calculator will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine cooling loads. <br /> The glazing(window)and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of 0.30. <br /> The incorporated insulation requirements are the minimum prescriptive amounts specified by the 2015 WSEC. <br /> Please fill out all of the green drop-downs and boxes that are applicable to your project.As you make selections in the drop-downs for each section,some <br /> values will be calculated for you.If you do not see the selection you need in the drop-down options,please call the WSU Energy Extension Program at <br /> (360)956-2042 for assistance. <br /> Project Information Contact Information <br /> DARIOTIS DEVELOPMENTS SFR CASINO RD DEANiDARlOTIS <br /> 903 W.CASINO RD 6306176TH SIT SW <br /> EVERETT,WA LYNNW000,WA 98037 <br /> Heating System Type: 0 All Other Systems O Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Design Temperature <br /> — — Design Temperature Difference(AT) 49 <br /> Everett Paine AFB eT=Indoor(70 degrees).Outdoor Desgn Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Conditioned Floor Area(sq ft) 672 <br /> Average Ceiling Height Conditioned Volume <br /> Average Ceiling Height(ft) 84 5,376 <br /> Glazing and Doors U-Factor X Area = UA <br /> 0.30 84 25.20 <br /> Skylights U-Factor X Area = UA <br /> 0.50 0 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Select R-Value . , No selection, <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> R-38 Vented i 0.027 672 18.14 <br /> Above Grade Walls(see Figure 1) U-Factor X Area UA <br /> R-21 Intermediate w ; 0.056 1,004 56.22 <br /> — I <br /> Floors U-Factor X Area UA <br /> R-30 = 0.029 I 672 19.49 <br /> .r. <br /> Below Grade Walls(see Figure 1) U-Factor X Area UA <br /> i Select R-value . <br /> No selection,l <br /> Slab Below Grade(us Figural) F-Factor X Le <br /> UA <br /> I Select conditioning I vr <br /> I No selection — <br /> Figure 1) F-Factor X Len <br /> UA <br /> Slab on Grade(see 1 <br /> Select R-value j No selection) --- <br /> Location of Ducts <br /> • <br /> Duct Leakage Coefficient <br /> Unconditioned Space <br /> 1,10 <br /> Sum of UA 119.06 <br /> Envelope Heat Load 5,834 Btu/Hour <br /> Figure 1.
